' DOMESTIC TELEGRAPH.

October 17, 1848.

To all whom it may concern; Be it known that I, J OHN RUSSELL, of the city, county, and Stateof New York, have. invented a new and useful Improvement in the Domestic Telegraph for Hotels, Pri vate Houses and other Places, called Bus-l sells Telegraphic Index, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification. Figure 1, is a front elevation of the tele graphic index. Fig. 2, is a vertical cross section of ditto, at the line a m of Fig. 1. Fig. 3 is a plan of the sliding frame for ringing the bell when the index is thrown out. Fig. 4 is a plan of the sliding frame for drawing in the index.

Similar letters in the figures refer to corresponding parts. a

The nature of his invention consists in connecting the wires, leading to the several rooms of the hotel or other building to which the telegraph is applied, to a series of inclined levers combined with sliding bars, spiral springs, weighted levers, and

suspended plates marked with the several numbers of the rooms, with which the wires communicate, combined with a bell, hammer, and suit-able mechanism for operating the same, and inclosed in a suitable .case ar+ ranged conspicuously in the room'of the.

clerk or servant whose duty it is to attend to answering the bell; in such a manner, that when a bell-pull of a room is drawn, the plate, containing the number of the room in which the summons is made, will be caused to fall below the part of the case covering the same, and exposed to the View of 5 the servant, and remain down until drawn: up by him; and simultaneously with its;

descent, the hammer will be caused to strike the bell, to call the attention of the attendant to the number down, thus making one bell answer for all the rooms of the hotel,

or other building in which the apparatus is view the number of the room in which the bell pull is drawn; so that should the attendant be absent at the time of the summons, the number Will remain down until his return, and render a second summons unnecessary.

A is the oblong case inwhich the levers,; &c., necessary for operating six numbers are I arranged, secured firmly against. the wall.

UNITED STATES PATE T orries;

The lower part of this case is partiallyopen, being formed byparallel longitudinal/boards n ron n d fro i l r esentd QC, are weighted levers, bent near their centers to resemble an acute angle, and suspended at that part to the horizontal shafts or rods B, B, which are inserted through p ilings h m; said e s "be n h l 'ii t e r'p es, herequire tance ap rt, by

nuts a, and shoulders a, and having 'a' preponderating weight at one end, by r'easonof th nd be ng madelarg r th the opposite one.

D re rs, suspende t h l ght ends of the e s y pin and'hav ng ircu a plates d cl secured to their lower ends,- on which the respective numbers of therooms a lee' blym rkedr v inclined levers, suspended by E, E, are

horizontal shafts or rods .12, b, ,onwhich they move as fulcrnms, being kept in their places above the levers .G, C, by shoulders their w r en s; g nst which the .yveig lited ends of the levers C, C, rest.

g, formed on the inclined levers F1, sus;

G G are wire rods, attached to the in ,clined levers, near their upper ends, and extending through the end of the case to the *4; inclined positions, after being drawn oby the outside, and having perforated shoulders h,

on their outer ends,'whi ch rest against anY oblong plate i, on the outside of the ca'se,-

for preventing the upper ends of the inclinedlevers, from being forced beyondfthe l a .85 n nuts, 6, f; a curved an unded of the pawl elevated;

bearings j, secured to the top) and back A, of the case, and having a hook is, at one end, to which is attached the end of a spiral spring Z, attached at its o osite endto a pin in theback of the case.

H is a smaller bar, arrangedparallel to the one above named,.and secured to oneend of the same, outside the inclined levers E, by horizontal rods m m, extending from one to the other, on the right hand ofthe upper endsiof the inclined, levers; i

I 1s'a pawl turning on a pin, inserted in .the bar H, near one end, and havingan angular'lip it or projection, at one end, which rests agalnst a pin 0 projecting from the side of the bar H, for keeping the opposite end J is a crooked lever, bent near the middle to resemble an obtuse angle, and turn ng on a pin 10, at. that ,part, as afulcrum, 1n-

serted in the back of the case below the sliding bar, and having ahook p, formed on its lower end, to which is'attached the upper end of a spiral spring, q, attached at its lower endto the back of the case, for keeping the upper end of the'lever against the pawl I.

. the bell.

K is another lever, also bent to resemble an obtuse angle, and turningon the pin p,

as a fulcrum, at its bent part, outside the lever J, and having ablock of iron or hammer 1*, attached to its lower end for striking I, is a semi-spherical bell, secured to a right angled plates fastened to the back of the case.

M is a pin projecting from the side of the lever J near its lower end, designed to strike against the under curved edge of the upper part of the lever K,when the lever J is turned on its fulcrum, by the pawl, and cause the hammer to bemoved from the bell. N is a pin projecting from the inside of the lever K near its upper end, and resting against the left edge of the lever J, above its fulcrum.

0 1s a horizontal slldlng b-ar,arranged below the bar H, and moving in bearings t by the lower ends of the inclined levers Q, is a spiral spring attached at one end to a hook 'v, projecting from the upper edge of the sliding bar 0, and at the other'end to a pin inserted in the back of the case.

R is ametallic block or stop secured to bar, parallel with the ones the back of the case, against whichthe end of the slidingbar O strikes and rests.

To illustrate the operation of the index, I 'will suppose the bell pull of room No. 2

. connected by wires to the wire rod G, to be drawn. This will cause the lower end of the inclined lever E to move to the left and turn the weighted lever C on its fulcrum, and cause its preponderating weighted end, to be transferred from the right to the left hand side of its fulcrum,when it will fall by its own "gravity on the rod u,'and

plate (Z containing the number, will be caused todescend and appear to view below the part of thecase, m by which it was covered, and simultaneously with these results, the upper end of the inclined lever E, moving to the right will strike against the rod m, secured to the end of the sliding bar H, and move the same with it, causing the pawl I, at the opposite end of the bar, to also move and turn the lever J, on its fulcrum p, and the pin M, near its lower end, :to strike against the under curved edge, ofthe upper end of the lever K, having a block or hammer 1', on its lower end, andto turn said lever on itsfulcrufm, until the bell-pull is let go, when the sliding bar H' and pawl I, and lever E, resting against the rod m,

connecting one end of the parallel bars H, H, together, will be drawn to their original positions by the spiral springs Z, F; and the hammery", caused to strike the bell L, by the combined agency of its own grav ity, and the pressure of the upper part of the lever J, exerted against the pin N, by the spiral springg. The lower sliding bar 0, is then drawn to the right, which causes the rod it, upon which the weighted end of the lever G, rests, to turn said lever to its original position, and the numbered plate cl, to be raised. This is done by the servant after he has seen the number that he is summoned to answer. 1 n

It will be observed from the foregoing description, and-reference to the drawings, that the inclined levers E, E, on the upper rods m, m, against whose lower ends, the upper ends of the weighted levers rest, act independently of each other; and that no matter which of the wire rods attached to them are drawn, the hammer will be caused to strike the bell, and the number, corresponding with the number of the room to which the wire attached to the shoulderof said wire rod, communicates, caused to descend below'the part of the case covering the same and exposed to full View, and that it must remain in that position until the I the call, thus the evil experienced in other arrangements, is avoided, of having thenumber drawn up out of sight by the next summons from another room before the arrival of the .servant whose duty it was to answer the first call.

In Fig. 1, the portion 00 Fig. 2 of the case is removed in order to show the operative parts and the numbers 1 and 2 raised. The dotted lines represent the'positions these numbers would assume, when thrown down below the front'of the case. No. 6 is represented as thrown down below the board w of the case in front of the same. The other numbers are all represented as raised. 7

The case may be made of any required length and depth to contain any required number of indexes, by the number of boards :1? of the case, beingincreased, in proportion to the number of indexes, and wires.

I do not claim to be the original inventor of combining mechanism for the purpose of simultaneously striking the alarm and exposing the number of the room whence the alarm is given, by the use of a single bell and then concealing the number before the summons is answered as this invention has been patented, but,

What I do claim as my invention is The particular combination and arrangement of the sliding bars H, O, pawl I, bent levers J and K, hammer a", bell L, levers E E, tumblers O 0, bars D D, springs Z, g, F, Q, and case A made with apronsw arranged at different levels and pro ections in the manner and for the purpose herein set forth by which an alarm is given simultaneously with exposing the number and causing it to remain exposed until drawn in and concealed by the person summoned or other person in attendance in a manner different from the mode heretofore patented, being much more simple, effectual, and economical than any of'said modes of domestic telegraphing. I In testimony whereof I signed my name before two subscribing witnesses.
